WILL GIVE 20 POINTS
Oksanka [162]

Answer:

The answer is B

Step-by-step explanation:

75 + x = 90

First, Virginia had to write an equation to solve for x.

75 - 75 + x = 90 - 75

Second, Virginia used the subtraction property of equality to isolate x.

x = 15

Third, "x = 15" was the answer Virginia got after subtracting 90 and 75.

75 + 15 = 90

Finally, she had to verify her answer

Given the following system of equations:
kompoz [17]

Answer:

(D) Divide the first equation, -4x + 8y = 16 , by 2.

Step-by-step explanation:

Given:

-4x + 8y = 16 \ \ \ \ equation \ 1

2x + 4y = 8 \ \ \ \ equation \ 2

We need to find the operation performed on equation so as to get resultant equation as:

-2x + 4y = 8

2x + 4y = 8

From Above we can see that there is no change in equation 2 with respect to resultant equation.

Also Resultant equation is simplified form of equation 1.

Simplifying equation 1 we get;

-4x + 8y = 16

We can see that 2 is the common multiple on both side.

Hence we will divide equation 1 with 2 we get

\frac{-4x}{2}+\frac{8y}{2}=\frac{16}{2}\\\\-2x+4y=8

which is the resultant equation.

Hence (D) Divide the first equation, -4x + 8y = 16 , by 2 is the correct option.

Katen [24]

Answer:

I'll answer the first one. Neither vehicles are crossing the speed limit since both are under 40mph.

Step-by-step explanation:

6 miles every 10 minutes = 36 miles every hour.

15 miles every 25 minutes = 36 miles every hour.

Speed limit = 40 mph

Neither vehicles are crossing the speed limit since both are under 40mph.

Hope this helped! :))
